To all whom it 'may concern.' i

Be it known thatI, ORION YoUNGBLooD, a citizen of the United' States, residingV at Boonville, in the county of Warrick and Statel of Indiana, have invented certain' new and useful Improvements in Seed-Hulling Devices, of which the following is a 'speci-1 fication.

This invention relates to certain new and useful improvements in seed hulling de! vices, andthe primary object of the inventiongis to provideV an attachment for wheat separators by means of which clover/alfalfa, grass seed, etc., may be hulled.

Another object of the invention is to `provide a device of the above kind which embodies the desired qualities of simplicity and durability of construction, and ease of manufacture and operation.

'Briefly described, the attachment `em bodies a feed chute adapted to be located beneath the discharge end of the usual weigher, a hulling device to receive the material from the chute, and a conveyor to` carry the material fromA the hulling device and Ydeliver it to a recleaner.

Vith the above general objects inv view,

and others that will become apparent as the nature of the invention is better understood, the sameconsists in the novel form, combination and arrangement of' parts hereinafter more fully described, shown in the accompanying drawings and claimed.-

In the drawings wherein like Yreference characters indicate corresponding parts throughout the several views,

Figure 1 is an'end elevational-view of an attachment constructed in accordance with thepresent invention and shown applied to a threshing machine.

lFigure 2 is a top plan view of the device shown in Figure 1, partly broken away.` 1

Figure 3 is a central longitudinal sec.-` tional vievv of the device. j

Figure 4 is a fragmentaryvside eleva, tional view of the same with parts removed, and i Figure 5 is a fragmentarysectionall view of one end of the threshing cylinder casing toillustrat`e a detail of the invention.

Referring more in detail vto thedrawings, the invention-consists of a hulling drum'5 provided with peripheral pins orteeth 6 and cooperating with the inner; surface .of a stationary concave hu'lli'ng"inember 7 which is valso provided-with teeth inra welliknownt manner.` i v i l v y The drum and concave hullingv member are disposed within va suitable casing 8 whichgis adjustable vertically-'by means of screws '9*a-ssociated with lugs 10 fixed to the ends ofthe casing, andbrackets 11 suitably mounted upon the threshing-machine atfthe ends of the casing 8. y rVertical movement of the casing8 is` permitted by'the provision of vertically elongated slots .12 in the ends thereof through which the shaft 13 of the drum 5 projects, the ends of ythis shaft being suitably mounted in bearings' 14C carriedy by brackets 15j that are mounted at the ends of the casing 8. By lthus adjusting the cas` ing, the concave member 7 'may bemoved toward and away from thelower portion of the cylinder 5 sofas to adjust these parts the required distance apart forobtaining best results in accordancewvith the nature. of the jmaterialvbeing hulled.` l

The drum 5 is preferably driven by a bevel gearing 16 at one end 'of the'shaft 13,0ne `of the bevel gears being placed upon thefshaft '17 extending at right angles tok the .shaft 13 vand suitablyfmounted in bear` ings uponthe threshing machine, as well as suitably` driven Vby means of-` the belt gearing atl one `end as at 18 from a drive shaft of the threshing machine. f

The casing 8 is preferably in the `form of a casting having the sha-pe ofiafcrossin plan with the central portion of the casting of cylindrical fornito accommodate the cylinder or drum 5, the end portionsof the casting being respectively formed to provide a casing as `at 419 for a' spiral conveyor 20 and to provide a `flared feed chute 21. The-conveyor 2 0 is arranged 'Wi-thin' the casing portion 19 and is' adapted to be rotatedby means-ofbelt gearingQTZ from the adjacent end 'of the" shaft 17, and the inner end of the portion 191is flared so that the material may be vreadily discharged` from the hulling drum' to the conveyorvv 20-along the entire length 'of said drum. VPreferably' ythe casing is formedfgof separablesections,` the `upperf'ones of which are lremovably. heldy in placeby screws`23, "or the like, so that access may rbe readily. had to; theinteriorfor re-l pairorcleaning purpolsesi; 1l;

The' feed chute 21 inclines towardv the drum 5=and yits outerendv is upturned'fas at Qfso. asto receive the material from the discharge spout 25 of the usual Weigher provided upon threshing machines. Also, the chute 21 is of flared form so as to deliver the material to the drum along its entire length, and in order to insure even distribution of the material to the drum,

the chute 21 is provided with diverging partitions as shown at 26 vin Figure 2.

In order to prevent escape of the material through the ends of the lcasing or through the slots 12 thereof, suitable slides 27 are mounted upon the shaft 13 so as to cover said slots 12 at all positions of the casing adjustments.

' The unhulled seed after passing through the separator to the weigher is discharged from the weigher into the chute 21 and the latter conveys the same onto the concave member 7 This seed is then effectively hulled when the drum 5 is placed into operation and the material is then discharged in the path of the conveyor 2O which carries it to the other side of the separator so as to deliver it to the recleaner. The device is preferably provided with suitable supporting legs or brackets which are adapted to be fastened to the separator by means of bolts, or the like, so as to permit easy removal of the device.

A device constructed in accordance with the above will serve as a valuable adjunct to threshing machines as it is possible to thresh both grain and seed.

From the foregoing description it is believed that the construction and operation, as well as the advantages of the present invention, willA be readily understood and appreciated by those skilled in the art.

Minor changes may be made without departing from the spirit and scope of the invention as claimed.l

What I claim as new is:
